The Houston Dynamo, who hold a two-goal lead going into Sunday’s Eastern Conference finals decider at D.C., got some good news on the injury front.

Defensive midfielders Adam Moffat (concussion) and Ricardo Clark (adductor strain) have returned to practice and are expected to play Sunday.

Moffat reports he had no ill-effects from Friday’s practice, and Clark said he was able to push himself hard in training and it went “pretty good.”

“Obviously, it’s going to raise your confidence because you know what kind of players those guys are,” Houston star Brad Davis told reporters. “Those guys are two good, hard players, and every time they step on the field they give everything they’ve got. When they’re not available, we definitely miss them.”

Houston needs a win, a draw or a one-goal loss Sunday to advance to the Dec. 1 MLS Cup final.
